The president is being biased because he is gay, would he be banned for a heterosexual slur?

Why would you ban someone for making a single gay slur? Wylted has repeatedly told people to kill themselves yet his account carries on. What even counts as a 'gay' slur? If you look at vispex's account you don't see anything even slightly offensive. I don't know him that well but this shows how the president operates...
